Se mueve un diente

In class today one of the five-year-olds, Manolito, whispered across the room to me, Sean, que se mueve un diente. That´s Spanish for Sean, my tooth is loose. That´s a big deal. Manolito went on to remind Alberto, his tablemate, that Ratoncito Perez - a little rat that corresponds to the Tooth Fairy in Spanish folklore - would be visiting him to give him a little present. Ratoncito Perez is gray and wears a red shirt, blue pants and gold-rimmed glasses, and carries a little bag - there you go in case you see him. I found out how he looks from an official description of him online. I don´t know if he travels outside of Spain though so you might not see him in the States.
